Felt I should add something further that shows a bit more detail.

This is taken 70MM 2.8 lighting is a soft box.

@ 70 mm, f 4

I've got it bad for this lens. :P

I have the EF 24-105 f/4L which I love and use as my 'walking around' lens. The 24-70 is bigger and heavier and overlaps the range of the 24/105, albeit faster. So, every time I'm about to hit the buy button on Amazon, I talk myself out of it because I just can't think of why I need the faster lens. And now, with talk of an update,....

But I'm about to begin a project of photographing Saint Louis at night. I want to spend a lot of the coming summer doing this. My camera for this job will be the 5DM2. Don't I REALLY NEED the 24/70 for that project? My 50mm 1.4 won't be enough, right? And the 24/105 is too slow, right? In fact, maybe I need the new 5DM3 with the new 24-70 II?

Go for it. Eat mac & cheese if a month if you need to cut costs. Turn down the thermostat and wear and extra sweater. I'll buy both if (when) they are announced - but only after a few months so the early productions models are gone.
